I don't know if it is a good idea or not.....but.
I have read on this site and many other sites about regulated fuel systems the pro's and con's (no dead head, flow tru.etc.). I have also read about the in tank mods, and all the issues of air in the fuel, fuel temp, pre-pump filters and so on. it seems that every thing involves the pump being required to draw fuel from the tank under vacuum and the problems with air entering thru the factory fittings when under vacuum, and issues of pump temp. OK has anybody looked at or tried a in tank pump like all fuel injected gas trucks have and then regulated to the proper pressure at the motor? Seems like this would help keep pump and fule cooler and greatlt limit the interduction of air in the system because the pump is submerged. Sorry being long winded just always thinking.

Thanks

 

Yep. It's been discussed before. Here's how kwik did his.

Great thought!! 2 years to late, but Great Thought!!!!!

 

Sorry about being late only been here for 6 months

 

Please know, just poking, promise, no insult was inteneded. I was sincere when I said great Idea!! you will fit nicely in this forum!! You couldnt find a better group of people!!

 

We only poke fun at people we like.
Welcome to FTE, and yes you will be glad to have your fuel pump in the tank.
It is a MUCH better way of doing it and according to the laws of nature, which BTW cannot be broken (tried to fly without wings lately? ), it is much easier to push the fuel toward the engine than to try and pull it toward the fuel pump.
That reason alone is what prompted me to migrate the fuel pump to the tank.

 

Yeah, I tried to push a chain in a straight line, ain't going to happen.

 

Kwik,

I recall during the initial discussion there was some concern about the wire's insulation not being diesel-rated.

Have you pursued that further?

I took a piece of the same wire that I used for the job in the first place and placed it in a vessel containing B50.
Those same two wires are still sitting on the shelf in the back room and the insulation is still just like the day that I put it in there.
That was what???, two years ago by now?
So I have decided that the insulation issue is really a non-issue.

 

Kwik, do you have a pump for each tank?
Do you have dual tanks? Guess I shoulda asked that first.
I didn't get to read the whole thing but I will tomorrow. Definately. Too close to time to log off.

 

So for clarification Dan- when doing this you leave the stock pump in place, correct? And you also need to do the Hutch Mod to avoid air in the lines as I understand.
I need to drop my tank to inspect the pick-up for blockage and I'd like to just tackle everything at once while I'm in there. Dropping that 55 gallon steel tank should be a fun job

 

Silly Neal... only one tank on the SD's

 

Kwikk. what pump did you use?
I found a delphi pump rated for diesel for in tank applications rate at 160 lph @ 600 kPa pressure. I don't know what specs. are required as for GPM or PSI.
Any specs would be great.

Thanks

 

For those of you that haven't read it yet (and it's obvious some haven't), go back up to post #2 of this thread and click on the link and read it for yourselves. A LOT of good information there.

Not a problem about being late. Besides, isn't it nice to have an idea your thinking about turn out to be a good one. Even better is someone has already done it, posted instructions on how to do it, and included pictures. Since he's been running it for 2 years without problems, your idea just went from concept to proven in a short time. Thanks to Dan's work, you can do this with no worries.
